    Area of Science:

    • Biotechnology
    • Molecular Biology
    • Protein Expression

    Background:

    • Insect baculovirus vector systems offer a rapid and convenient method for producing foreign gene products.
    • These systems are widely utilized in both academic research and industrial applications.

    Purpose of the Study:

    • To highlight the utility of insect baculovirus vector systems for expressing foreign gene products.
    • To discuss the successful high-level expression of biologically active vertebrate proteins using these systems.

    Main Methods:

    • Utilizing insect baculovirus as a vector for foreign gene expression.
    • Analyzing the processing and activity of expressed vertebrate proteins, including signal sequence cleavage and glycosylation.

    Main Results:

    • Successful high-level expression of numerous biologically active vertebrate proteins reported.
    • Correct cleavage of mammalian signal sequences observed.
    • Similarities in core glycosylation between vertebrate and invertebrate systems noted, with substantial differences in terminal glycosylation.

    Conclusions:

    • Insect baculovirus vector systems are effective for expressing biologically active glycosylated vertebrate proteins.
    • The ease and speed of these systems make them ideal for rapid analysis of gene products, especially after site-specific modifications.
